>Description:
	Attempting to link first stage compiler fails due to undefined external reference to cpp_pop_buffer in
	c-parse.o
>How-To-Repeat:
>Fix:
	The following patch fixes the problem but a better solution should be used instead. Presuambly the
	proper fix is an a simialr function somewhere else.
